While comparing Austinite and Bowenite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Austinite and Bowenite chemical formula.
Another important criteria for qualitative analysis of gemstones is Austinite and Bowenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Austinite and Bowenite Optical Properties during the identification of gemstone. Specific gravity of Austinite is 2.58-2.80 whereas that of Bowenite is 2.58-2.80.
